Greg was leaving his house in East Coast, USA. He was listening to music with the volume set to loud. Later on, Officer Henry and 2 paramedic vans responded to the crash. Officer Henry crosses the bridge. However, Greg was driving until he gets clipped by one of the paramedic vans. the other paramedic van goes off a ramp and crashes at the bottom. Due to loud music, Greg couldn't hear the sirens and also failed to give way at the intersection. This cost him his and 2 medics' lives.
